M Pelletier provided false information twice Owen Sound, Ontario

I purchased 6 side socket plugs plus a 7th at 33% off.  No shipping costs or extra costs were provided before the transaction went through. 

When I looked at what they will charge my credit card, it is

$60 for 6 sockets

$7.00 for extra one

Sub Total 67.00

PROCESSING $121.30

Total of order $188.30

I was stunned and called immediately to cancel.  Agent indicated it would be 12 to 24 hours to get processed and that I could not cancel until then.  That was February 27th.  Called back on Feb. 28th at 8:30 and provided the order number to the agent and was told they cancelled the order.

I called back later that day on February 28th just to reconfirm that the order was cancelled and Dave told me it was.

Tonight, March 1st, I see an invoice for $188.30 which will be taken from my credit card.

I am so shocked.

This, in my opinion, is fraudulent business practices.

First, the total of the order should be given prior to confirming the transaction.

I called twice to double check on the cancellation and it was never done.

I don't know what to do.  Should I call the credit card company? Better Business Bureau?
